Battery connector

Abstract

A battery connector includes an insulating housing, a plurality of contact terminals, conductive terminals and elastic elements which are disposed to the insulating housing. Each elastic element is restricted between the contact terminal and the conductive terminal. The insulating housing defines a plurality of terminal cavities and two inserting slots. Each contact terminal has two resisting arms slidably located in the inserting slots. Each resisting arm protrudes downward to form an abutting arm located in the terminal cavity. Each conductive terminal has two connecting slices inserted in the inserting slots, and a holding slice stretching in the terminal cavity. An electrical connection is realized between the contact terminal and the corresponding conductive terminal by means of the resisting arms electrically abutting against the corresponding connecting slices and the abutting arms electrically clamping the holding slice therebetween under the bias of the connecting slices acting on the resisting arms.

What is claimed is: 
     
       1. A battery connector, comprising:
 an insulating housing having a front surface and a rear surface opposite to the front surface, the insulating housing defining a plurality of terminal cavities penetrating through the rear surface and receiving grooves penetrating through the front surface and connecting with the terminal cavities respectively, two opposite inner sidewalls of each terminal cavity being recessed oppositely to form two inserting slots passing through the rear surface; 
 a plurality of contact terminals movably disposed to the insulating housing, each contact terminal having a base frame movably located in the receiving groove, a front end of the base frame being defined as a touching portion projecting out of the insulating housing through the receiving groove, rear ends of two opposite sides of the base frame extending rearward and being further arched oppositely to form two resisting arms slidably located in the inserting slots, a free end of each resisting arm protruding downward to form an abutting arm located in the terminal cavity; 
 a plurality of conductive terminals disposed to the insulating housing, each conductive terminal having a restricting slice against the rear surface, two opposite sides of the restricting slice bending forward to form two connecting slices inserted in the inserting slots, a bottom of the restricting slice bending forward to form a holding slice stretching in the terminal cavity, a rear end of the conductive terminal defining a soldering slice projecting out of the insulating housing, an electrical connection being realized between the contact terminal and the corresponding conductive terminal by means of the resisting arms electrically abutting against the corresponding connecting slices and the abutting arms electrically clamping the holding slice therebetween under the bias of the connecting slices acting on the resisting arms; and 
 a plurality of elastic elements of which each is located in the terminal cavity and restricted between the contact terminal and the conductive terminal. 
 
     
     
       2. The battery connector as claimed in  claim 1 , wherein two opposite sides of a rear end of the inserting slot are further concaved oppositely to form two fastening fillisters, two rears of a top edge and a bottom edge of each connecting slice protrude oppositely to form two wedging portions fastened to the fastening fillisters, the top edge of each connecting slice protrudes upward to form an interfering portion interfering with a top inner sidewall of the fastening fillister. 
     
     
       3. The battery connector as claimed in  claim 1 , wherein the base frame includes a base arm, two opposite sides of the base arm extend downward to form two propping arms, the base arm and the propping arms are movably located in the receiving groove, a front end of the base arm is arced forward and then bent rearward to form the touching portion, rear ends of the propping arms extend rearward and are further arched oppositely to form the resisting arms. 
     
     
       4. The battery connector as claimed in  claim 3 , wherein the rear end of each propping arm meanders rearward and outward to form a stretching arm located in the terminal cavity, a top of a rear of each stretching arm protrudes upward and then extends rearward to form the resisting arm. 
     
     
       5. The battery connector as claimed in  claim 4 , wherein a bottom of the rear of each stretching arm extends rearward to form a fastening arm, two opposite sides of a bottom sidewall of the terminal cavity are recessed downward to form two locating slots for locating the fastening arms therein. 
     
     
       6. The battery connector as claimed in  claim 1 , wherein a rear end of a bottom sidewall of the terminal cavity is recessed forward to form a gap, the rear end of the conductive terminal defines an L-shaped opening passing through the restricting slice and the holding slice, a lower inner sidewall of the opening bends downward and then rearward to form the soldering slice of L shape projecting out of the insulating housing from the gap. 
     
     
       7. The battery connector as claimed in  claim 1 , wherein the elastic element is a spring. 
     
     
       8. The battery connector as claimed in  claim 7 , wherein a rear end of a top of the base frame extends rearward to form a locating piece, a rear of the locating piece extends rearward to form a guiding pin substantially located between the resisting arms, the elastic element is worn around the guiding pin of the contact terminal and restricted between the locating piece and the restricting slice of the conductive terminal.
